Quadruplets. Quadruplets are much rarer than twins or triplets. As of 2007, there were approximately 3,556 sets recorded worldwide. Quadruplet births are becoming increasingly common due to fertility treatments.
Some names for these are: Twins for 2 fetuses. Triplets for 3 fetuses. Quadruplets for 4 fetuses.
Types of Quadruplets
Multizygotic quadruplets occur from four unique egg/sperm combinations. Monozygotic multiples are the result of a fertilized egg that splits into two or more embryos. It is possible for a split to occur more than once, producing monozygotic triplets or even a rare set of monozygotic quadruplets.
Quadruplets are four children who are born to the same mother at the same time.
Septuplets (7)
The McCaughey septuplets (born 19 November 1997, in Des Moines, Iowa) are the world's first surviving set of septuplets.
If the 12 – called duodecaplets – are all born alive they would represent a medical miracle and break the record of American mother Nadya Suleman, who recently gave birth to the world's longest-surviving octuplets.
– Decuplets: a combination of 10 of a kind.
Octuplets are a set of eight offspring born at one birth. An individual that is part of such a set is called an octuplet.
Quintuplets occur naturally in 1 in 55,000,000 births. The first quintuplets known to survive infancy were the identical female Canadian Dionne Quintuplets, born in 1934. Quintuplets are sometimes referred to as "quins" in the UK and "quints" in North America.
Meet the Record- Breaking Nonuplets.
Nonuplets are a group of nine, in the case of birth, nonuplets refer to nine babies who are born at once. The world's only nonuplets celebrated their first birthday earlier this year.
Monoamniotic-monochorionic Twins
This is the rarest type of twin, and it means a riskier pregnancy as the babies can get tangled in their own umbilical cords.
The world's only nonuplets - nine babies born at the same time - have safely returned home to Mali after spending the first 19 months of their lives in Morocco. The babies broke the Guinness World Record for the most children delivered in a single birth to survive.
Irish twins is the term for siblings born in the same calendar year or within 12 months of each other.
There are two types of twins – identical (monozygotic) and fraternal (dizygotic). To form identical twins, one fertilised egg (ovum) splits and develops two babies with exactly the same genetic information.
Sextuplets can be fraternal (multizygotic), identical (monozygotic), or a combination of both. Multizygotic sextuplets occur from six unique egg/sperm combinations. Monozygotic multiples are the result of a fertilized egg that splits into two or more embryos.
of twins at birth. OBJECTIVE: By convention, twins are labeled as twin A or twin B at the time of birth, depending on their birth order. However, antenatally twins are labeled as A or B according to their location relative to the birth canal. Antenatal labeling is usually established by prenatal ultrasound.
Identical, or monozygotic (MZ), twins have 100 percent of their genes—including those that influence risk for alcoholism—in common, whereas fraternal, or dizygotic (DZ), twins share (on average) only 50 percent of the genes that vary in the population (see figure). Common Environmental Sources.
Down syndrome is also referred to as Trisomy 21. This extra copy changes how the baby's body and brain develop, which can cause both mental and physical challenges for the baby. Even though people with Down syndrome might act and look similar, each person has different abilities.
While the typical definition of Irish twins is two children spaced 12 or fewer months apart, people do sometimes use the term more loosely to include children born 13, 14, or more months apart, particularly if the children end up in the same grade in school.
The largest pregnancy ever recorded was of a woman in Los Angeles, California in 1945, who gave birth to 10 twins, making a total of 12 babies. She went on to give birth to 16 children in total, with the 10 twins being the largest number of babies born at once.
